' This invention relatesto the 'art of machines adapted for use vinreolain'i'ing usedjournal box walste and refers particularly to a structure ernployed to raise and lower and reciprocate a set '5 :of lingers for lthe purpose of agitating waste in a bath'of` hot oil as wella's' to intermittently move :that waste'from' one end to the other of that bath. The structure is so designed that a set oi iingers may be reciprocated fore and aft ina tank adapted "1o to hold heated 011 se as tof give the tiene therein a like reciprocatory motion soas to thoroughly flush the waste with the'oil.' Further, the structure isdesigned to remove the fingers frein engagement with thewaste'ina relative *forward position and then carryfth'e fingers back to. a rear position toreeng'age with' the'- waste land then .continue the reciprocatory motion to the end that the .wasteis gradually worked from the rear end of the -bathto the forward Zendby disengagement and reengagement of the' fingers in walls of the tank l0 and have the bell cranks 18 relatively spaced apart positions. v

It is an object of our ,invention to provide a very simplet-iming mechanism tobi-ing about the above indicatedresults without the useof chains. A further'import'ant object of the invention is to confine the timing and driving lmechanism to within awconipactV space adjacent the tankwithin which the waste is operated upon. f These and other objectswill become apparent in the following description of the invention as il'- lustrated more or less diagrammatically in the accompanying drawings, in which` Fig. 1 i s afragmentary' side elevation ot a andits immediate driving connection, and

- Fig. 6, a further detail in fragmentary top plan view of the timing'mechanism.v

Like characters of reference indicate like parts throughout the several views in the drawings.

`Weemploy a tank'lO adaptedto'hold a considerable volume of lubricating oil preferably in a heated condition, LWithinthis tank we mount a horizontally disposed screen' 11 'on which waste is :receivedand supported. This screen 1l is here 5 shown as beinglon'gitudin'ally slotted so as to receive therethrough from the under side afplurality l l Yare mounted by their upper ends on the bar 20 vto beheld in fixed relation thereto and to hang ldownwardly therefromy parallel one with` the otyertically disposedngers 12, These fingers Aare -xed to .8 frame 131carried below'the screen rotatably mounted transversely of the tank 10 in ccleime. (el. c 1411-715 spaced relation below the screen 11 and each has xed thereto the cam blocks 16 and 17 respectively. 'Ihe frame 13 rests upon these cam blocks 16 andfi' and the blocks are so formed that upon 'simultaneous rotationof the shafts 14 and 15, the 60 frame 13l and its'iingers 12 will be raised and lowered'accordingly. Each of these blocks is here shown as being substantially rectangular in shape with one end curved around from one side vto the Votherwhereby upon rocking the block, the frame o@ mayv ride down over` this curved portion on' to a straight portion as indicated in Fig. l from the solid line position to the vdash line position. That is, the diierence in the elevation of the frame 13 from the raised to the lowered position is produced by revolving the blocks around from their upper longitudinally disposed positions to-horizontally disposed positions, 'the Yblocks being ylonger thanthey are wide.

eem shafts 14 and 15 extend through me side 73 and 19 fitted thereto respectively on the same sideof the tank. A slide bar 20 is carried slid'- lably'by the brackets 21 and 22 in a horizontally disposed position above the cranks and a lower slide bar 23 Vis slidably carried by the brackets 24 and 25 in parallel arrangement with the upper bar 20 but spaced an equal distance below the shafts. These cranks 18 and 19 are iixed to the positions to hold the frame 13 upwardly, the arms 'of the cranks arev disposed symmetrically to each have an arm turned horizontally and forwardly and the other arm vertically downwardly. From the Ihorizontally disposed armsof these cranks extend the links 26 and ZTrespectively to pivotally engage with downturned arms carried by the bar 2. Also fromv each of the downturned arms of the cranks is a link 2`8pivotally interconnecting it 95 with an upturned arm carriedl by the slide bar 23, the links 28 being carried horizontally'to therear Yin parallel arrangement with the bar 23 while the bars 20jand 23 and interengages these bars by pins 31 and 32 extending through slots in the respective ends of the arm. l

A pair. of Verticaly disposed guides 33 and 34 other, the guides being here shown as being secured to the rear side of the bar 20 to hang downwardly back of the bar 23 without connection in any way therewith. A cam is provided to have a circular periphery of a diameter permitting it to be slidably fitted and carried between the two guides 33 and 34. This cam is connected to an arm 36 by a pin 37 located eccentrically of the center of the cam and the upperend of the arm 36 is fixed to a sleeve 38 rotatably Ycarried on the end of a transverse shaft 39, the shaft 39 extending entirely across through the tank 10. An arcuate slot 40 is provided in the cam 35 to have its center of curvature at the center of the pin 3,7`and a` pin 41 carried in a fixed position on the arm 36 Vslidingly extends within this slot as a stop limiting the rotation of the cam thereby about the pin-37.

Power from some source (not shown) is transmitted to a spur gear 42 mounted on a transverse shaft 43 which incidentally dives an unloading conveyor 44.v This gear 42 is here shown, Fig, A2, as driving an idler gear 50,' a second idler gear 51 loosely mounted on the shaft 14, and nally the shaft 39 through another gear 44 which isv fixed on the shaft 45 which extends transversely across the tank to vcarry a mutilated gear 46 on its outer end back of theguides'33 and 34. On the shaft 39 isl mounted an eccentric 47 from which leads a shaft 48 to have its rear end pivotally connected with the frame 13 whereby rotation of the shaft 39 will cause fore and aft reciprocation of the frame 13. The gear 46 is fixed to the shaft 45 in a position such that the teeth thereon will be brought around into mesh with the teeth of the spur gear 49 which is fixed tothe sleeve 38. This spur gear 49 is here shown, Fig. 6, as being in two sections, one being an integral part of the sleeve 38 and the other being fixed or keyed to the shaft 39.

In operation, the train of gears turning with the gear 42 isset in motion to have the fingers 12 reciprocate fore and aft as the frame 13 is Vshifted over the cam blocks 16 and 17 by the,l shaft 48. Beginning the sequence of operations, for'example, with the fingers 12 in the upper positions as indicated in Fig. 1, these fingers will be given an initial foreand aft reciprocation while in the upper positions. This reciprocation inthe upper positions will continue as long as that part of the gear 46 having no teeth thereon is traveling past the gear 49, but since the gear 46is being continually'driven by the` shaft 45, the teeth on this gear will eventually'come around to mesh with the gear 49 to cause rotation ,of the gear 49. When this gear 49 revolves, that is that part of the gear fixed to the sleeve 38, then the arm 36 will be swung around to carry the cam wheel 35 against the rear guide 34 so as to shift the slide bar 20 to the rear, this movement of the bar 20 pulling the links 26 and 2'! along therewith so as to tend to rock the shafts the two bars. 20 and 23 and the interconnecting members,

both shafts 14 and 15 will be'simultaneously rocked alike distance. By reason of the peculiar hook-up between these two bars 20 and 23, the shafts 14 and 15 are effectively-retained at either end of their permissible travel against accidental shifting since the links between the bars and the bell cranks come around to right angular positions to form braces requiring an application of power to displace them.

Following the rotation of the gear 49 to thus lower the fingers l2 as above indicated, the gear 46 continues in its travel leaving the fingers in their lower positions although they continue to reciprocate fore and aft but out of contact with the waste on the screen 11. The waste is thus allowed to soak for a time interval and the position of the eccentric 47 on the shaft 49 is so arranged in relation to the location of the teeth on the gear 46 that when the teeth again come around into contact with the gear 49 to return the cam blocks 16 and 17 to their upper positions, the ngers willv return into the waste at a position rearwardly of that from which they were withdrawn when the cam blocks were lowered. The following reciprocation will then of course move the waste ahead a distance equal to the spacing longitudinaly between the iingers 12.

Referring again to the gear 49 and itsjcompanion'part which is fixed to the shaft 39,r the gear is thus split in order to provide an additional drive to thefshaft 39 through the shaft 45 and gear 46 while the arm 36 'is being revolved t`o shift the frame 13. That is, while thev gear 49 is being revolved to turn the arm 36, the shaft 39 is then being turned by the gear 49 and the gear 46.
